Frequencies

Frequency band definitions e.g. where is SHF, X band, J band. What frequencies are GPS

Hard Sums

Laplace, Fourier and z transforms, trig, calculus etc.

Constants and Conversions

e.g. Boltzmann's constant, imperial conversions, resistivities, heat capacities and conductivities

Floating Point Processors
